11 October 1941 | Dutch Jewish boy, Heinrich Lange, was born in Amsterdam.

He was deported to #Auschwitz from #Westerbork in July 1942. He was murdered in a gas chamber after arrival selection with his mother Berta. His father Hans perished in the camp in September 1942.

I just took the square root of 90,000 in my head. That’s big.

Millions of Americans are working without pay in Federal and Air Traffic Controller jobs while White House continues construction of 200 Million$ Ballroom during the Government Shutdown. Unbelievable people voted for this illiterate clown 👇

Manannán by Máiréad Ní Ghráda 1940 Irish Language scifi book might be the first fiction piece with the use of a gravity assist. And the first Mecha robot outside of Japan.

But it's not in the Irish library service or buyable online

Coming soon!

Written by historian Leanne Calvert, @unioflimerick.bsky.social ‘Pious and Promiscuous’ offers a previously unseen glimpse into how ordinary people faced life’s most significant milestones as members of a closely knit Presbyterian community in the long 18th century Ulster.

The moment you unearth an elusive piece of the story, and it all clicks together is a high that these people will chase forever and never so much as glimpse in the distance. Your brain is so much more powerful and creative than any AI shill wants you to believe.

One year ago, I started posting observations on BlueSky, and I have thoroughly enjoyed the journey. I've put all 196 observations from the last year into a little book called "What I noticed along the way". I hope you enjoy it. drive.google.com/file/d/1w0zL...

In the Samaria Gorge on the island of Crete, Greece, lies a very deep cave with a continual cold spring waterfall. To reach it, you have to swim about 100 meters in 10 degree (C) water. I spent time thinking about hypothermia I was so cold. Nice payoff tho.

Walls of the cave direct you to a small bright opening in which a cold mountain spring falls to bright turquoise water. 

Along with Denali Mountain and Bryce Canyon, this is the most majestic place I’ve ever been. 

My teeth rattling even as I could stand in only waist deep water kept me from fully enjoying it,, but no chance I was missing this just for some discomfort. 

It seemed to get progressively colder tho so this is about as close as I got. In later days I’ll post a shot looking back thru the caves. The video I took is really the best indicator of the beauty here but I dunno if I can post that here or not. I may try in the comments later today.

I feel like a broken record, but I have to keep saying it over and over again: a farmer bailout won’t do much of anything because the market is gone. There will be no incentive to plant next year.

The bailout will help payoff farmer debt to the banks. That’s all.

Use only water or fresh air on tear gas or pepper spray.

No milk, vinegar, antacids, urine, etc. and especially not in eye.

Thank me later,
